Why 300 Microns Matters
Research by Dr. John Goeser and on-farm data show that reducing corn particle size enhances rumen starch digestion, resulting in more efficient nutrient use and improved milk production. While 400–600 micron grinds were once considered adequate, today’s performance-minded dairies and nutritionists are aiming lower and Star Blends is delivering.
Grinding to 300 microns increases starch availability, boosts net energy intake, and enables cows to get more from every pound of feed, often without increasing feed intake. It also supports good rumen fermentation when properly managed, helping farmers balance productivity with animal health.
Precision You Can Count On
What sets Star Blends apart isn’t just our ability to grind corn finely, it’s how precisely and consistently we do it. Many mills test their particle size only occasionally, if at all. At Star Blends, we analyze particle size daily using a full, ASABE-compliant process (ANSI/ASAE S319.4). This includes a full Ro-Tap sieve stack (U.S. Nos. 6–270), mechanical agitation, and standardized flow agents. Every batch is verified in-house, so you get real numbers, not assumptions.
We closely monitor both geometric mean diameter (dgw) and geometric standard deviation (Sgw) to ensure not just a fine grind, but a uniform one. This uniformity improves ration formulation and helps reduce variation in herd response, so you can rely on consistent feed performance from batch to batch.
Performance Meets Practicality
With rising feed costs, dairies are constantly seeking ways to stretch every input. Steam-flaked corn is effective but expensive. Our finely ground corn offers a cost-effective alternative that still delivers excellent feed efficiency and milk output. The VersaMil®’s direct drive technology gives us precise control over roll speed and differentials, ensuring consistent grind quality that rivals much more expensive feed solutions.
Trusted by Nutritionists and Producers
Nutritionists trust Star Blends for feed inputs that are backed by real data. By providing consistently ground corn at 300 microns, we help improve ration accuracy and support better energy modeling in TMRs. This leads to fewer surprises, more consistent digestion rates, and better herd performance across the board.
